WEATHER-STRIP.

Specification of Letters Patent. Patented Sept. 14;, 1920.

Application filed February 7, 1920. Serial No. 357,075.

This invention'relates to weather strips for windows and particularly to a weather strip designed for use at the top and bottom of a window. The object is to provide a metal strip adapted to be fastened to the window sill or the head piece of the windo frame in such a manner as to engage the window sash when the windows are closed, so as to prevent rattling of the window and to keep out wind and rain which would otherwise penetrate between the window sash and frame.

In the drawings,

Figure 1. is a perspective partly in cross section showing my weather strip in place with the upper and lower windows seated.

Fig. 2 is a sectional view showing the upper window sash withdrawn from the head piece of the frame.

Fig. 3 is a sectional view showing the lower window sash upraised from the sill.

Let a represent the window sill; b the window amb and c the head of the window frame. The sash stops for the upper and 1 lower windows are indicatedby characters (Z2 and d respectively. ried at the outside of the window is indicated by the letter 6; the sash stop along the head of the window frame is indicated by 71. and the stop on the window sill by 2'. The sill itself is frequently cut away to form the sash stop 2'. v The same purpose, however, would be served as in the case of a separate stop.

The upper window is indicated by g, the lower window by f. The cross-railof the upper window is indicated by g2 and the meeting rail by 98. The lower cross rail of the lower window is indicated as f2 and the meeting rail as f3. As the weather strip used for the top of the window is the same as the one used at the bottom only one will be described.

The blind stop car-.

The top of the window frame'serves the same purpose as the sill with reference to the position ofthe weather strip and its method of attachment.

The sill a is longitudinally grooved to receive'a downwardly projecting ledge 103 formed on the weather strip is. The weather v strip then extends along the face of the sill and is provided with an upwardly projecting tongue 1 192 adapted to be received in a longitudinally extending groove Z in the cross-rail of the sash. The sash stop '11 is provided with a horizontal groove i2 adapt ed to receive an outwardly projecting ledge L4 formed on the upwardly extending inner flange 705 of the weather strip. This flange 705 is bent inwardly so that when it is engaged' by the sash it will spring outwardly into the groove i2. This flange/c5 is formed of spring metal so that it will resistingly yield outwardly as it contacts withthe side of the sash and thus form a more nearly perfect wcather-tight joint with the sash than would be otherwisethe case.

It will be observed that the inner edge of the sash is beveled so thevertical movement of the sash will not be impeded by the weather strip. y

The weather strip may be formed, as shown, of one piece of metal. What has been said, of the weather strip applied to the bottom of the window would be equally true of its counterpart applied to the top of the window. I i

What I claim is: p

1. In a window, the combination of a window sash provided with a groove, :1. weather strip adapted to be attached to the window frame, said strip provided with a tongue adapted to be received in the groove in the window sash, said strip bent upwardly to form a yielding flange adapted to abut the side of said sash so as to yield resistingly outwardly therefrom as the sash is seated thereagainst, said flange turned outwardly at its upper extremity to form an outwardly projecting tongue adapted to be received within a groove in a window stop. said stop provided with such groove.

2. In combination with a window sill and sash adapted to be seated thereon, a metal weather strip secured to the sill provided with a vertical flange adapted to be received within a groove in the sash, said strip bent upwardly at its outer edge to provide a yielding flange inclined toward the sash adapted to be en aged thereby and yield resistingly outward therefrom when the sash is seated on the sill, such yielding flange turned outwardly at its edge forming a tongue adapted to be received within a groove in the outer stop, an outer stop grooved to receive said tongue, said Window sash grooved to receive said vertical flange. 10

In testimony whereof, I sign this specification.

WILLIAM SCHNEKENBURGER.
